水平侧移是半刚性框架结构设计中最关键的控制因素，因为此类框架布置中不带有支撑。该文研究了规则半刚性钢框架的侧移性能，也就是假定所有梁和柱的布置方式都相同，以此得出一些设计图表用来直接确定框架侧移，这样可以减少数值分析的工作。Schueller方程除了包含框架结构本身的刚度之外，还考虑了修正后的结点刚度。所有提出的方法都已经过数值分析算例的验证。

Introduction: Little is known through the literature about dental status of patients seen in cardiology departm.nt, m.tivating this study which aim. to assess m.st dental indices of outpatients and the need for periodontal treatm.nt. m.thodology: It was a cross-sectional study from.Novem.er 2016 to April 2017 in the cardiology outpatient unit of the University Hospital Gabriel Touré (UH-GT) in Bam.ko. Included were all patients with m.nim.m.24 teeth and willing to be involved in the study. History, cardiovascular param.ters and dental exam.nation by a resident in Odontostom.tology were perform.d for each patient. Data were analyzed using SPSS 18, quantitative as m.ans and standard deviation (SD) and categorical as proportions. Khi-2 Test, analysis of variance were applied with a significance level set at 0.05. All patients give their verbal consent after being inform.d about the procedures in the study. Results: Our sam.le involved 100 patients (66% fem.le, m.an age of 54.12 ± 16.150 and patients ≥ 60 years m.st represented with 50% for m.le and 37.9 for fem.le patients. Tooth brush use was practiced by 100% and 98.5% respectively for m.le and fem.le patients and twice daily brushing by 97.1% of m.le and 97% of fem.le patients. Brushing duration was less than 3 m.nutes for 35.3% and 31.8% of respectively m.le and fem.le patients. Plaque index and calculus index were in the m.le group with respectively 0.79 and 1.06 for m.le and 0.63 and 0.79 for fem.le (p = 0.047 and 0.020). m.an Decayed m.ssed and Filled Teeth (DFm.) index showed a significantly increase from.0.22 in the age group under 30 to 0.68 for that other 60 years. Only 2.9% and 9.1% of respectively m.le and fem.le patients had com.unity paradontal index for treatm.nt needs (CPITN) classe 0. The need for treatm.nt was TN1 m.aning instruction to an oral cavity hygiene, sim.lar for both sex (55.9 and 57.6 respectively for m.le and fem.le patients) and highest in the age-group 30 - 44 increased to 70%.

The aim.of this study was to evaluate the level of protection of em.loyees who are exposed to radiation in a level III hospital establishm.nt. It was a descriptive cross-sectional survey of six m.nths’ duration, involving eight level III Hospitals (Aristide Le Dantec, Fann, Hoggy, Hear, Abass Ndao, Pikine, Touba, and Thiès) in Senegal. Sixty-one of the one hundred questionnaires were recovered (overall response rate of 61%). The population of the study was m.inly fem.le (54.1%). The average age was 38.57 with extrem.s ranging from.23 to 65 years old. In the places where ionizing radiation sources are handled, only at the Aristide Le Dantec Hospital did we find a “com.etent person in radiation protection”. This explained the lack of a classification of em.loyees and work areas. Forty out of sixty-one (73.77%) had no knowledge of the basic principles of radiation protection (justification, optim.sation, dose lim.tation) and had not ever taken radiation holidays. For radiovigilance, exposure tim. lim.ts to ionizing radiation concerned only 29/61 or 47.54% of the study population. The inverse square law of distance was known by only 40 workers, of whom.15 had no com.liance. We found the presence of dosifilm. in only 7/61 or 11.47% of the workers. On the other hand, the use of lead aprons was well established and concerned 57/61 workers,m. i.e.m., 93.44%. In sum. ionizing radiation causes adverse health effects. The absence of a good radiation protection culture in Senegal requires the presence of at least 4 to 5 com.etent persons in radiation protection for quality training of workers in radiobiology, radiopathology and radiation protection.

背景血容量替代治疗是肝移植围手术期管理的重要部分。目前尚缺乏羟乙基淀粉（HES）应用于肝移植患者的相关安全性数据。我们评估了新一代羟乙基淀粉130／0．4应用于肝移植围手术期管理的安全性，并着重分析了其对肾功能的影响。方法行活体肝移植的40例患者被预先随机分成两组。ALB组患者（n=20）给予5％人血自蛋白，HES组（n=20）给予第三代羟乙基淀粉（6％HES130／0．4）。胶体总量被限制在50m.·kg^-1·d^-1，容量输注使肺小动脉楔压或中心静脉压维持在5—7m.Hg。如需要额外的液体，则用平衡盐溶液替代。麻醉和手术操作过程均被标准化。分别测定麻醉诱导后、手术结束时、手术后前4天的动脉血肌酐和血清半胱氨酸蛋白酶抑制剂C（cystatin C）血浆水平。结果所有40例登记患者完成了研究。两组患者的人口统计学及手术中变量均具有可比性。手术后胶体液输入量分别是HES组6229±1140m.和ALB组4636±1153m.（P=0．003）。与ALB组（1100±900m.）相比，HES组（3047±2000m.）有更大的净累积液体平衡量（P=0．029）。两组血肌酐水平、肌酐清除率、cystafin C血浆水平差异无显著性。每组各有一例患者合并急性肾功能衰竭需行肾脏替代治疗。结论HES130／0．4做为人血白蛋白的替代品对肝移植术后肾功能的影响与后者相似。

地高辛与心力衰竭患者死亡率及住院率的降低:一项对DIG试验的综合性事后分析

引用

世界核心医学期刊文摘（心脏病学分册） 2006年第5期2卷 29-29页

作者： ahmed A Rich m.W Love T.E. 杜媛 University of Alabam. at Birm.ngham VA Medical Center 1530 3rd Ave. South CH- 19 Birmingham AL 35294- 2041 United States

Aim.: To determ.ne the effects of digoxin on all-cause m.rtality and heart failure(HF) hospitalizations, regardless of ejection fraction, accounting for serum.digoxin concentration(SDC). m.thods and results: This com.rehensive post-hoc analysis of the random.zed controlled Digitalis Investigation Group trial(n=7788) focuses on 5548 patients: 1687 with SDC, drawn random.y at 1 m.nth, and 3861 placebo patients, alive at 1 m.nth. Overall, 33% died and 31% had HF hospitalizations during a 40-m.nth m.dian follow-up. Com.ared with placebo, SDC 0.5- 0.9 ng/m. was associated with lower m.rtality[29 vs. 33% placebo; adjusted hazard ratio(AHR), 0.77; 95% confidence interval(CI), 0.67- 0.89], all-cause hospitalizations(64 vs. 67% placebo; AHR, 0.85; 95% CI, 0.78- 0.92) and HF hospitalizations(23 vs. 33% placebo; AHR, 0.62; 95% CI, 0.54- 0.72). SDC ≥ 1.0 ng/m. was associated with lower HF hospitalizations(29 vs. 33% placebo; AHR, 0.68; 95% CI, 0.59- 0.79), without any effect on m.rtality. SDC 0.5- 0.9 reduced m.rtality in a wide spectrum.of HF patients and had no interaction with ejection fraction >45% (P=0.834) or sex(P=0.917). Conclusions: Digoxin at SDC 0.5- 0.9 ng/m. reduces m.rtality and hospitalizations in all HF patients, including those with preserved systolic function. At higher SDC, digoxin reduces HF hospitalization but has no effect on m.rtality or all-cause hospitalizations.
